maven - Gradle-从单个项目生成和安装多个jar

Question

我可以构建我需要的 jar -但是使用gradle install我得到了错误

A POM cannot have multiple artifacts with the same type and classifier. Alr eady have MavenArtifact a:jar:jar:null, trying to add MavenArtifact a:jar:jar:null.

根据文档，为每个存档设置不同的 baseName 可以解决此问题，但不能解决此问题。

我已经尝试过Gradle 2.2.1，以防万一。

相关的build.gradle

task package1 (type: Jar) {
    baseName = "a1"
    include "**/packageA/**"
}

task package2 (type: Jar) {
    baseName "a2"
    include "**/packageB/**"
}

task package3 (type: Jar) {
    baseName "a3"
    include "**/packageC/**"
}
artifacts{
    archives package1,package2,package3

}

我不想为Maven POM设置不同的分类器或类型。那是唯一的选择吗？

Answer 1

我按照https://gradle.org/docs/current/userguide/publishing_maven.html中描述的方法使用gradle publish进行了此工作

task package1 (type: Jar) {
    baseName "a1"
    version "0.1"
    from (sourceSets.main.output){
    include "com/packagea/**"
    }
}

task package2 (type: Jar) {
    baseName "a2"
    from (sourceSets.main.output){
    include "com/packageb/**"
    }
}

// We use the publishing task instead of gradle install to deploy the jar into the local MAVENREPO
publishing {
    publications {
        publisha1(MavenPublication) {
            groupId 'com.my'
            artifactId 'a1'
            version '0.1'
            artifact package1 
        }
        publishb1(MavenPublication) {
            groupId 'com.my'
            artifactId 'b1'
            version '0.1'
            artifact package2 
        }
}
